I can also verify that Screeble will destroy battery life. I used it on my Droid for 2 years no problem so naturally when I upgraded I was going to use it again.
First day with my handset I didn't install it (didn't auto install) second day installed it and noticed severe battery drain and EXTREMELY high OS %'s (35-75%)
Screebl is terrible and it does not play nice with newer Motorola devices on Gingerbread for some reason.
